I currently ride Ntorq 125 (2018). Looking to sell it off and get a bike.

USES: 
* My daily commute is 60 km approx. (30+30) to work. Which is around 1400 km monthly.
* From city to a short stretch of highway, then to curvy rural road with broken patches every now & then, some are almost like offroad, through mud & broken bricks road and finally uphill climbs (I am from a hilly area, but not that high hills like Himachal Pradesh or Sikkim).
*not so aggressive as a rider in terms of speed as I mostly ride through traffic jam, broken roads or hilly curves. Can't exceed 75 kmph in most of those areas. 

PRIORITIES:
* atleast 40 kmpl mileage.
* Single seat is ideal for pillion comfort & ease of access for ladies.
*Also, handle position, seat cushion & suspension should be decent to cater rider comfort since I have to travel such distance every day (mostly solo).

I shortlisted 4 bikes - N160 single seat usd, XSR155, Ct125x & Ronin.

I added a CT125x (2023 variant) as I am getting it for ₹50,000 only in decent condition. Wondering if removing the headlight fairing + drl is legal? And most importantly would it serve my purpose?

Otherwise XSR & N160 are most ideal bikes. Ronin is the second last option for me as I don't wish to own another TVS, but if that is the best, then I'll just go with the black one. 

Please enlighten me experts. 

(Not so expert in bikes, only rode 4 bikes till now, mostly 2 times each bike, Hness 350, Hornet v1, Pulsar 125 & Bs4 Classic 350. H'ness gave me the best experience).

Need first bike suggestions! N160 single seat usd v/s XSR 155 v/s Ct125x/110x vs Ronin base model.
